- Renewed January 31, 1933 2 Claims. (01. 107-28) '10 whereby the amount of batter delivered may be varied at the will of an operator.

A further object of the invention relates to the provision of a device of the character described which may be moved over the molds to fill the same with batter and may be subsequently withdrawn out of the path of operation of the molds which are usually rotatable or movable to effect the baking operation.

More specific objects of the invention relating to the improvement of operating parts will become apparent from the following description read in conjunction with the accompanying drawings, in

which:

Fig. 2 is a vertical sectional view taken through the measuring devices;

Fig. 3 is a vertical section taken on the plane indicated at 33 in Fig. l; and

Fig. 4 .is a horizontal section taken on the plane indicated at 44 in Fig. 3. V

A baking mechanism including suitable molds is diagrammatically illustrated at 2. As' is common in this type of machine there are two sets of molds arranged side by side, in the present in.- stance there being twelve molds in each group, six being in each of two lines. Accordingly, there are provided ,two duplicate sets of discharging .40 and measuring devices to deliver batter irom a the casting is adjustably carried an arm 14 upon 1 the outer end of which is secured a-U-shaped supporting frame 16 arranged to carrythe mold filling device proper, which is provided with flanges 55 overlying the sides ofthe U-shapedframe l6 and of the'cylinder.

which is secured in position by means of a bar 20 embracing the free ends of the U-shaped frame and secured thereto by suitable wing nuts. As will be obvious iromiFig. l, in which the device is shown in its operative position swung over the members of a set of molds and stopped in that position by the engagement of lug 10 with the stop face-of collar 12, the'device may be swung about post 4 to an inoperative position so as to permit closure of the molds and rotation-to effect the baking operation. I

The mold filling mechanism proper comprises a suitable receptacle 22 in which a supply of batter may be placed. .The bottom of this receptacle is closed by a casting 24 which carries duplicate measuring and discharging devices. casting is bored as illustrated in Figs. 1 and 2 to receive a bushing 26 which provides a receiving cy1inder for a slidable cylinder 28. The casting and bushing are provided with apertures'30' as illustrated whereby the batter may flow from the receptacle into cylinder 28, from which his discharged through nipples 32 provided with openings aligned with lower openings in bushing 26. -A series of openings 34', the purpose of which will be apparent hereafter, are. also provided and extend through the casting and the bushing."

* Within each cylinder '28 are secured a pluare "securedzjwithin'the cylinder 28 and closely surround rod 40 so asto subdividethe'cylinder into a number of small chambers and prevent the flow of the semi-fluid batter from one chamber to another. The cylinder 28 is provided with openings '44 at its top adjacent partitions 36' as shown and with similar openings 46 at its bottom directly opposite the openings 44. Apertures 48 are also provided, as indicated,:in the lower side The two cylinders are secured at their rear ends by a plate 50 which embraces threaded extensions and which is secured to the'cylinders by means of nuts 52 threaded onthe extensions. The piston rods 40 pass freely through these extensions. The iorward ends of thecylinders are similarly connected by a plate 54 which is en gaged over threaded extensions and which issecured to its cylinder by means of nuts 56. The piston rods also extend freely through these forward extensions. .Suitable means such as, for example, pins extending from the cylinders through either of the supporting plates prevent rotation of, the cylinders and maintain the upper The and lower apertures in proper positions to align with the openings in the bushing.

Plate 54 carries a forwardly extending member 58. Slidably mounted on this forwardly extending member 58 is a slide 60 secured through the medium of sidewise extending ears 62 to the forward ends of piston rods 40. Pivotally mounted in slide 60 is a pawl 63, the nose of which is arranged to engage at proper times with a notch 64 formed in member 58. A spring 66 serves to press the pawl 63 in position to engage its nose with the notch. A cam plate 68 carried by a supporting member 69 secured to the casting 24 cooperates with the upwardly extending free end of pawl 63 to release the same from engagement with the notch as the pawl is carried to the right as viewed in Fig. 2. Slide 60 is movable by means of a handle 61 pivoted to the slide and secured to one end of a link 65, the opposite end of which is pivoted to the supporting member 69.

slidably mounted in the lower portion of slide 60 is a member 70 in which is pivoted a pawl 72, spring pressed as indicated by a spring '74 so that its nose will engage within a notch '76 formed in member 58. A cam '78 serves to act on the free end of pawl 72 to lift its nose out of engagement with notch '76. A pin is carried by the rear end of member '70 and is arranged to engage the forward end 82 of the cam 78 to limit forward movement of the assembly. Member '70 is provided with a threaded extension 84 which is engaged by an internally threaded nut 86 pivotally mounted in a slot in the forward end of slide 60.

In the operation of the device, the receptacle 22 will be filled with batter and the device then swung about post 4 to the position indicated in Fig. 1, in which nipples 32 overlie the respective openings in the molds. By now imparting a movement to lever 61 in a counter-clockwise direction, as viewed in Fig. 2, slide 60 will be moved forwardly or to the right, as illustrated in this figure. The nose of pawl 63 is now engaged with slot 64 so that during the movement of slide 60 to the right member 58 is moved therewith, thusmoving the cylinder 28 and pistom 42 as a unit to the right, pistons 42 being now engaged with partitions 36, as illustrated in Fig. 2. During this composite movement of the pistons and the cylinder to the right, openings 44 in the cylinder are brought into alignment with openings 30 in the casting 24 and bushing 26. At the same time openings 48 are brought into alignment with the openings in nipples 32. As such movement of the rod proceeds, pawl 63 is disengaged from notch 64 by cam 68 so that slide 60 may continue its movement to the right independently of member 58, which will remain stationary. The positive stoppage of member 58 and the cylinders 28 is effected by engagement of plate 50 with the rear end of casting 24, which engagement occurs at the same time that pawl 63 is released from notch 64. At this time openings 44 are aligned with openings 30 and openings 48 are aligned with openings 32, or in the case of the most forwardly opening 48, the alignment takes place with the most forwardly opening 34, as illustrated at the right of Fig. 2. During continued movement of the handle, the pistons 42 will move to the right away from partitions 36, drawing into the cylinder 28 batter from receptacle 22 through openings 30 and 44. The movement of slide 60 to the right continues until stop 80 engages end 82 of the cam 78. 11 0 16.6

to change this stroke of the pistons during the operation of drawing batter into the cylinder, it is only necessary to rotate nut 86 in the proper direction, whereby block '70 is adjustable relatively to slide 60 to procure an earlier or later engagement of stop 80 with the end 82.

In order to discharge the batter in cylinder 28 into the molds, the handle 61 is given a clockwise movement as viewed in Fig. 2. At the extreme end of the first operation just described, the nose of pawl '72 drops into engagement with notch '76 so that as the handle is moved in a counterclockwise direction, serving to move slide 60 to the left, the member 58 is moved to the left therewith, thereby eifecting a movement of the cylinders to the left to a position aligning openings 46 with the nipples. reached plate 54 engages the casting, limiting further movement and at the same time pawl '72 is disengaged from notch '76 by cam 78. Further movement of slide 60 to the left moves the pistons 42 toward the partitions, forcing the batter out through openings 46 and nipples 32 into the molds.

The apertures 48 serve during the above operation to permit-the inflow or outflow of air to or from the space behind pistons 42. During the first described operation of filling the cylinder 28 these apertures 48 are aligned with the nipples so that the air behind the pistons is forced outwardly therethrough. During the second operation of discharge from the cylinder the openings 48 are alinged with openings 44 so as to permit an influx of air behind the pistons.

From the above description, it will be seen that accurately measured quantities of the batter may be delivered to the molds, the quantity being readily and predeterminedly changed by a simple adjustment of nut 86.

What I claim and desire to protect by Letters Patent is:

1. A mold filling device comprising a receptacle, a casing having an opening therein and a passage joining the opening with the receptacle, a cylinder slidably mounted in the opening, said cylinder having a closure wall therein, a piston movable within the cylinder towards and from said wall, said cylinder having intake and discharge openings therein, and said casing having a discharge opening therein, and operating connections between the cylinder and piston whereby, successively during a cycle of operation, in the charging stroke the cylinder and piston initially move together until the discharge openings are disaligned and the passage and intake openings are aligned, and then the cylinder stops and the piston withdraws from the wall to draw a charge from the receptacle into the cylinder, and in the discharging stroke the cylinder and piston initially move together until the passage and intake openings are disaligned and the discharge openings are aligned, and then the cylinder stops and the piston approaches the wall to force the charge from the cylinder, said operating connections including latches arranged to connect the cylinder and piston during the initial portions of the strokes and means for subsequently tripping the latches.
